北京恒业世纪科技股份有限公司7月招聘面试题面试题面试官常问到的一些题目整理如下:问题 Q1:是否使用过functools中的函数?其作用是什么?可用的回答 :python自带的 functools 模块提供了一些常用的高阶函数,也就是用于处理其它函数的特殊函数。换言之,就是能使用该模块对可调用对象进行处理。functools.cmp_to_key(func)functools.total_ordering(cls)functools.reduce(function, iterable, initializer)functools.partial(func, args, *keywords)functools.update_wrapper(wrapper, wrapped, assigned, updated)functools.wraps(wrapped, assigned, updated)问题 Q2:如何在Python中删除文件?可用的回答 :使用命令os.remove(filename) 删除文件 或 os.unlink(filename) 删除快捷方式问题 Q3:跨域请求问题django怎么解决的(原理)?可用的回答 : 1. 启用中间件 2. post请求 3. 验证码 4. 表单中添加%csrf_token%标签 问题 Q4:是否使用过functools中的函数?其作用是什么?可用的回答 :python自带的 functools 模块提供了一些常用的高阶函数,也就是用于处理其它函数的特殊函数。换言之,就是能使用该模块对可调用对象进行处理。functools.cmp_to_key(func)functools.total_ordering(cls)functools.reduce(function, iterable, initializer)functools.partial(func, args, *keywords)functools.update_wrapper(wrapper, wrapped, assigned, updated)functools.wraps(wrapped, assigned, updated)问题 Q5: Django重定向你是如何实现的?用的什么状态码?可用的回答 : 使用HttpResponseRedirect redirect和reverse 状态码:302,301 问题 Q6:如何在python中使用三元运算符?可用的回答 :三元运算符是用于显示条件语句的运算符。这包含true或false值,并且必须为其评估语句。其基本语法为:三元运算符是用于显示条件语句的运算符。这包含true或false值,并且必须为其评估语句。其基本语法为:on_true if expression else on_false问题 Q7:如何将数字转换为字符串?可用的回答 :要将数字转换为字符串,请使用内置函数str()。如果需要八进制或十六进制表示,请使用内置函数oct()或hex()问题 Q8:如何删除python数组的值?可用的回答 :可以使用pop()或remove()方法删除数组元素。这两个函数之间的区别在于前者返回已删除的值,而后者则不返回。问题 Q9:scrapy和scrapy-redis的区别?可用的回答 : scrapy是一个爬虫通用框架,但不支持分布式,scrapy-redis是为了更方便的实现scrapy分布式爬虫,而提供了一些以redis为基础的组件 为什么会选择redis数据库?因为redis支持主从同步,而且数据都是缓存在内存中,所以基于redis的分布式爬虫,对请求和数据的高频读取效率非常高 什么是主从同步?在Redis中,用户可以通过执行SLAVEOF命令或者设置slaveof选项, 让一个服务器去复制(replicate)另一个服务器,我们称呼被复制的服务器为主服务器(master),而对主服务器进行复制的服务器则被称为从服务器(slave), 当客户端向从服务器发送SLAVEOF命令,要求从服务器复制主服务器时,从服务器首先需要执行同步操作,也即是,将从服务器的数据库状态更新至主服务器当前所处的数据库状态 问题 Q10:什么是PYTHONPATH?可用的回答 :它是导入模块时使用的环境变量。每当导入模块时,也会查找PYTHONPATH以检查各个目录中是否存在导入的模块。解释器使用它来确定要加载的模块。算法题面试官常问到的一些算法题目整理如下(大概率会机考):算题题 A1:二叉树的最大深度题目描述如下:可做参考的解答如下:class Solution: def maxDepth(self, root: TreeNode) - int: if root is None: return 0 else: left_height = self.maxDepth(root.left) right_height = self.maxDepth(root.right) return max(left_height, right_height) + 1 算题题 A1:两个排序后的列表的中位数题目描述如下:There are two sorted arrays nums1 and nums2 of size m and n respectively.Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n).You may assume nums1 and nums2 cannot be both empty. Example 1:nums1 = 1, 3nums2 = 2The median is 2.0Example 2:nums1 = 1, 2nums2 = 3, 4The median is (2 + 3)/2 = 2.5求两个列表合并后的中位数。时间复杂度要求O(log (m+n)1. 直接sorted后取中位,时间复杂度为O(m+n)log(m+n)。2. 不用全部排序,本质上是一个求第k(s)小的数。 时间复杂度(O( (m+n)/2 )还是没到要求的 O(log (m+n),此版beat 43%56%。 # 打印真的是很慢,只打印一条很小的数据2.方法就会只能beat 7%.3. 最后是 O(Log(m+n) 的思路:求第k小的数的时候,有一种方法是每次去除 k / 2 个数,剩余 1个时就找到了最终要找的数。a = 1, 2, 4, 6b = 3, 5, 7, 9此时的 k 为 8 / 2 = 4.k/2 = 2则对比 a与b的第2个数也是下标为2-1哪个较小,较小的一组去除。然后循环即可。因为是排过序的列表,不论哪一个列表中,去除 k/2 个数都不会去除目标。因为只有k的一半,又是排过序的,假设ak/2bk/2:1. 去除的值只有k的一半,2. 选择的是较小的那一组,那么组合起来:b:k/2-1 + a

有关 Assigned的说法哪个是正确的?( )

A.其他三项都不对

B.Assigned的作用是判断一个对象是否为 Nil,如果是Nil,返回 True,如果不是Nil,返回 False

C.Assigned的参数可以是对象或者方法,或者是一个指针

D.Assigned的作用是判断 Assign过程是否已经完成。

I don’t think it advisable that Tim( )to the job since he has no experience.

A.is assigned
B.will be assigned
C.be assigned
D.has been assigned

答案:C
解析:
考查虚拟语气。在It is advisable/important ...that ...的句型中,that 引导的主语从句中的谓语应用虚拟语气,形式为“(should) +动词原形”,should 可省略。故本题选C。句意:我认为指派蒂姆做这项工作是不明智的,因为他没有经验。
